Ultrasonic Power Supply Module
The Ultrasonic Power Supply Module generates ultrasonic energy at the resonant
frequency of your Converter-Booster-Horn Stack. The Ultrasonic Power Supply Module
contains three main circuits.
• 320VDC Power Supply: converts AC line voltage to +320VDC for the output power devices.
• Output circuit – matches the impedance of the output power device to the Converter-Booster-
Horn Stack; and provides feedback to the Control circuit.
• Control circuits: perform the following functions:
Provide drive signal to output power device.
Determine true percentage of ultrasonic power used over a range of amplitudes.
Allows control of the resonant frequency.
Control starting amplitude.
Provide overload protection for the Ultrasonic Power Module.
Store operating frequency of last weld (frequency memory) and use the stored frequency as a
starting point for the next weld.
Check and update frequency memory on start-up.
Provide switch-selective starting ramp times (Start).
DC Power Module
The Switching DC Power Module rectifies, filters, and regulates the AC voltages from the
Line Transformer into DC voltages for the System Control Module.
